Comment 473 for bug 620074

I've tried stress also.
I have 2 Gb og memory and 1.5 Gb swap

With swap activated stress -d 1 hangs my machine

Same does stress -d while swapiness set to 0

Widh swap deactivated things runs pretty fine. Of couse apps utilizing syncronous disk-io fight stress for priority.

There must be a reasonable explanation on why everything stops when swap is activated. Even a simple app like "dstat" stalls.
